Can someone please advise if there are any restrictions on trains or public transport services within the city centre at present due to the recent bombings? And if so, which areas are affected. We arrive very late Friday night and have appointments we need to keep on Saturday morning and want to know if we need to allow additional time due to road blockages, diversions etc. Also is there an obvious increase in security/policing on the streets in the city centre. Thank you in advance.
